Washington, October 12 (ANI): Researchers have discovered a potential new target for the debilitating skin condition eczema, and demonstrated that by blocking it, they can lessen the disease in mice. <\/p>\n
More than 15 percent of children suffer with eczema, or atopic dermatitis, an inflammatory skin disease that in some cases can be debilitating and disfiguring. <\/p>\n
In eczema, immune T cells invade the skin and secrete factors that drive an allergic response, making the skin itch. <\/p>\n
Dr. Raif Geha, of Boston Children's Hospital, and his collaborators has shown that scratching the skin precipitates the condition by encouraging an influx of other immune cells called neutrophils. <\/p>\n
These neutrophils secrete a lipid called leukotriene B4 that calls in more neutrophils, and more importantly, potent immune T cells that are the hallmark of eczema. These cells cause inflammation that aggravates the skin further. <\/p>\n
The investigators suspected that blocking the onslaught of these cells might slow down the disease or even stop it in its tracks. <\/p>\n
Furthermore, Dr. Geha and his colleagues wondered whether the production of leukotriene B4 served to recruit T cells to the site of mechanical insult. And indeed that was the case. <\/p>\n
\"We showed that a drug that blocks the production of leukotriene B4 blocks the development of allergic skin inflammation in a mouse model of eczema,\" said Dr. Geha. <\/p>\n
His team also found that deleting the receptors on immune cells that bind to leukotriene B4 had a similar effect. <\/p>\n
\"Our findings suggest that neutrophils play a key role in allergic skin inflammation and that blockade of leukotriene B4 and its receptor might provide a new therapy for eczema,\" said first author Dr. Michiko Oyoshi. <\/p>\n<\/p>\n
